I got the keys to my broken heart
I'm gonna run them up and down your car
Boy, you gonna need a body guard
For all the drama I'm about to start
Know what this is? Always a cheater
'Cause you looked me in the face and I believed you
And I'm over all the lies you told
Now I'm calling just to let you know
I'll be your crazy ex-girlfriend
I'm never gonna leave you alone
You'll wish I never was your girlfriend
Or that you ever treated me so cold
Cold, cold
Call me your crazy ex-girlfriend
Cold, cold
Call me your crazy ex-girlfriend
I drop the speakers from the highest floor
I'm on a mission, gonna start a war
If I were you, I would lock your door
You got me madder than ever before
Know what this is? Always a cheater
'Cause you looked me in the face, and I believed you
And I'm over all the lies you told
Now I'm calling just to let you know
I'll be your crazy ex-girlfriend
I'm never gonna leave you alone
You'll wish I never was your girlfriend
Or that you ever treated me so cold
Cold, cold
Call me your crazy ex-girlfriend
Cold, cold
Call me your crazy ex-girlfriend
And I don't like the way you look at her with those eyes
No, I don't like, but I'm your crazy ex-girlfriend
I'll be your crazy ex-girlfriend
I'm never gonna leave you alone
You'll wish I never was your girlfriend
Or that you ever treated me so cold
Cold, cold
Call me your crazy ex-girlfriend
Cold, cold
Call me your crazy ex-girlfriend
I'll be your crazy ex-girlfriend
I'm never gonna leave you alone
You'll wish I never was your girlfriend
Or that you ever treated me so cold
Cold, cold
Call me your crazy ex-girlfriend
Cold, cold
Call me your crazy ex-girlfriend
